Your old O ring may look O.K, but it will have gone hard and brittle, losing the structural integrity it needs to do it's job. Don't be tempted to re-use the old one!
This O ring covers many types of models, we cover many of these with an online 'parts list' fiche. You may like to browse the fiche for your model, you may be surprised at the stock we carry at CMS. We probably hold more new old stock for Bike, than any other dealer in Europe!
Please check the model application list carefully before placing your order.
